Freezer machine is a crucial technology for ensuring food quality and extending shelf life, capable of rapidly lowering the core temperature of food products within a very short time. There are three commonly used types of freezer machine, what are the three types of freezers: fluidized-bed quick-freezers, tunnel-type quick-freezers, and quick-freezing cabinets.
1. Fluidized Freezing Machine
This machine utilizes a powerful cold airflow to suspend food particles in the air, creating a “fluidized” state. Cold air is blown at high speed from beneath a perforated air plate, uniformly cooling the food and achieving rapid freezing.
Функции:
Fast Freezing Speed: Food is completely enveloped by cold air within the airflow, resulting in short freezing times.
Non-Sticking: Each item freezes individually without clumping.
Applications:
Primarily used for granular foods such as peas, corn kernels, shrimp, blueberries, strawberries, diced meat, and other standalone quick-frozen products.
2. Tunnel-Type Quick Freezer
This continuous-type quick-freezing equipment processes food placed on a conveyor belt through a tunnel-shaped freezing chamber. Air-cooled units blow low-temperature airflow from the top or sides, gradually cooling the food to freezing temperatures during transport.
Функции:
High Adaptability: Suitable for various food forms, including meat, seafood, pastries, and cooked foods.
High Capacity: Suitable for continuous operation on medium to large production lines with strong freezing capability.
3. Blast Freezer
This intermittent freezing equipment typically features a sealed cabinet structure. After food is loaded, a powerful forced-air cooling system rapidly lowers temperatures, enabling static rapid freezing of products.
Функции:
Low Investment Cost: Cost-effective, suitable for small-to-medium enterprises or experimental production.
High Flexibility: Temperature and airflow parameters can be adjusted for different food types.
Ideal for Multiple Varieties and Small Batches: Independent freezing cycles can be set for each product during each operation.
Of course, in addition to the above types, there are other kinds of quick-freezing equipment. We can recommend the most suitable freezer machine based on your specific materials.
